Zoi aZZ whom itmay concern: I '1 Be t known that I, ERNEST MAKER, aminzen of the United States, residing at Santa Rosa, in the county ofSonomaand .State of California, have invented certain new and usefulImprovements in Coffee-Urns and,

Heated Dispensing Attachments Therefor, of which the following is aspecificatlon.

This inventionrelates to aneilnproved coffee urn and heated dispensingattachment therefor particularly designed for use in lunch rooms orother public places and has as its primary object to provide anarrangement wherein pipes will bo led from the milkand coffee chambersofthe'urn alon the counter of the lunch room and provide withgfa'ucets atsuitably spaced points so that coffee and'milk maybe drawnffrom the urnat the said faucets without the necessity'of eachtinie making a tripftothe coffee urn and whereinthecolfeeand milk pipe will bekepthot by'thSteam r hewfi hamber; a i

provide an arrangement wherein the coffee and milk pipes will beinclosed- 'within the And the"inventionhas as a still further objectjtoprovide an arrangement wherein coflee' may be" made within the urn inthe usual ,manner and wherein "the coffee and milk pipesa's well as thesteam pipe inclosingithe said coffee and milk pipes' will all beprovided with valves to permit the es:

said'chamber cannot, therefore, flow out of theupper end ofthe blow-offpipe. Con- ,nected to theflupper end of the pipe section Specificationof Letters Patent. Patented Aug, 21, 1917.

Thehorizontally arranged portion of thezblow-oflpipe may, of course, be ofany suitable length to extend the desired distance longitudinally ofthe. counter 11. Theypipe section 24, at its end opposite the elbow23,is provided with a simi- I lar'elbow 2'5 and upstanding from the saidFig. '2 is a fragmentary sectional v ew elbow 25 is apipe section 26terminating at lts upper end above the level of the coffee Coffee withinthe 26 is a-suitable springpressed blowsoff valve 27 normally closingthe said blow-oli pipe while, at the same time, steam from the coffeechamber 14 of the urn may readily flow through thesaid pipe. Y a aLeading from the lower extremity of the cofiee chamber 14 of the urnandarranged within the blow-off pipe is a coffee dispensing pipeincluding a pipe section 28 in which is arranged a suitable shut-ofl?valve 29'. The pipe section 28, at its outer extremity is fitted throughthe coupling 21 of the blow-oii pipe and receives an elbow 30' to whichis connected a depending pipesectioii31' within the pipe section 22.From the pipe section 31, the coffee dispensing pipe is then continuedthrough the pipe sec tion 24 of the blow-off pipe as indicatedat 32 andterminates in an upstanding pipe within the steam blow-off pipe is amilk dis pensir'ig pipe including a pipe section 35 in which isinterposed ashut-off valve 36. Connected to the outer extremity of thepipe section 35, is an elbow 37 to which is attached a pipe section 38leading through the coupling 19 into the pipe section 20 of the blow-oilpipe. From the pipe section 38, the milk dispensingv ipe is thencontinued through the blow-o pipe as shown at 39 and terminates in anupstanding p pe section 40within the upstanding pipe section 26 of theblow-off pipe. The pipe section 40 projects to a point above the upperGXtI'GlTlityoi themilk chamber 15 of the urn 10 and at its upperen'd isequippedwith an escapement valve 41 similar to the valve 34 of thecofieedispensing pipe. 5

, Connected to the horizontally arranged portio'n of the coffee and milkdispensing pipes at suitable longitudinally spaced points thereon, arepairs of dispensing raucets 42, the faucetsof each pair being arrangedadjacent'each other and communieating with the said pipes respectively.Leading from the; faucets 42 areb'ranch pipes 43 threaded through thehorizontally arranged pipe section 24 of the steam blow} on pipe andconnected at their inner ex tremities with couplings interposed in thecoiiee and'milk dispensing pipes. Any suitable number 'of pairs ofthe'faucets 42. may, of ceurse, be em loyed depending upon the leirgthoif'the horizontally arranged portions ofthe coii'ee and milk dispensingpipes and the blow-oil pipe.

As will now be clear, the valves 29 and 3G may be closed, when coffeemay be made within-thecofiee chamber 14 of the urn 10 in the usualmanner with the heat from the lower portion of the urn rising to heatthe milk within the milk chamber 15. At the same time, steam from thecoiiee chamber 14 may pass through the blow-off pipe to escape at thevalve 27. This steam in thus flowing through the blow-oii pipe will, ofcourse, heatth'e coffee and milk dispensing pipes arranged therein andafter such pipes have become so he'ated,' the valves 29 and 36 may beopened when the coffee and milk will enter the coffee and milkdispensing pipes to be kept heated by the steam from thecoiiee chamber,Consequently, the coffee and 'nilk may at any time be dispensed attl1e-faucetsj42 without the necessity of the attendant making atrip-totliecofiee urn each time itis desired to pour a cup of cofiee.Theadvantage of this arrangementwill at once be obvious and especiallyin large lunch rooms or other public places where a fee and milk withinthe dispensing pipes therefor will, at all times, be kept hot byutilizing the escapingsteam from the coffee chamber for this purpose"while any steam rising from the coffee and milk within the dispensingpipes therefor will be permitted to: escape from the valves 34 and '41upon the upper ends of the coifee and milk dispensing pipes.
